COLLISION AVOIDANCE METHOD FOR TRANSMITTING DATA FROM MULTIPLE WIRELESS TIRE CONDITION SENSORS - A collision avoidance method for transmitting data from multiple wireless tire condition sensors on a vehicle is executed by each wireless tire condition sensor having a unique ID and multiple different wake-up times. After the sensor is operated to sense data, the method has steps of reading the ID and computing a determination value with the ID and a variable, selecting one of the wake-up times according to the determination result, and after the selected wake-up time expires, transmitting the sensed data. As the selected wake-up times of the sensors differ from one another, data collision at the receiving end arising from data transmission from the sensors can be avoided. Additionally, besides the wake-up time, a time gap between data transmitted twice consecutively from each sensor can be employed to achieve data collision avoidance.

DETECTING A TIRE ROTATION ON A TELEMATICS-EQUIPPED VEHICLE - A system and method for detecting a rotation of the vehicle tires between different wheel locations. The method carried out by the system involves obtaining and storing TPM sensor identification numbers and their corresponding tire locations. Next, the system checks the sensors periodically to determine if any of the sensors have changed tire location. Based on that change, the system determines if a tire rotation has occurred; for example, by matching changes in sensor positions with known tire rotation patterns. This approach allows the system to detect and record a tire rotation, as well as to take some automated action, such as subsequently notifying the vehicle owner when the next scheduled tire rotation is due.

APPARATUS FOR DETECTING POSITIONS OF WHEELS OF VEHICLE AND APPARATUS FOR DETECTING TIRE INFLATION PRESSURE USING THE SAME - An apparatus for detecting positions of wheels of a vehicle is provided. In the apparatus, a triggering signal is transmitted from the body side to each transceiver mounted at each wheel. In each transceiver, the strength of the received triggering signal is measured and formatted into a frame of data to be transmitted to a receiver mounted to the vehicle body. The strength of the triggering signal is used to detect wheel positions by determining that each transducer is disposed at which wheel. The receiver determines if there is a reply of the flame of data containing the strength when the triggering device transmits the triggering signal. When no replay comes from the transceiver, the strength of noise is measured in the transceiver in response to a command from the receiver. When the noise strength is less than a threshold, the receiver commands an alarm member to issue alarm.
